Bart thought about retorting that she would have to catch him before she could shove a sword down his throat, but thought better of it. "Sorry." He apologized instead, but pushed the door open and headed inside. At this point, since she was already here, Rose could either come along and meet Kara like she said she would-- or stand out in the cold and call for a cab.
He held the door open for her and moved out of the way to let her inside, though his attention was back in the house, towards the living room. "Kara? Kara, are you still here?" Hopefully she hadn't flown home already... he really wanted her and Rose to meet.
